Product Overview

The ATSAM3U2EA-AU is a SMART SAM3U series 32-bit Flash Microcontroller based on the high-performance ARM Cortex-M3 RISC processor. It operates at a maximum speed of 96MHz and features 128kB of flash memory and 32kB of SRAM. The peripheral set includes a high speed USB device and PHY at 480Mbps, high-speed multimedia card interface for SDIO/SD/MMC, a 16-bit external bus interface supporting NAND flash, three USARTs, two TWIs (I²C), four SPIs, I²S, four PWM timers, three 16-bit timers, RTC, 8x12-bit and 8x10-bit ADC. The architecture is designed to sustain high-speed data transfers. The multi-layer bus matrix, multiple SRAM banks, PDC and DMA support parallel tasks and maximize data throughput. The SAM3U1C operates from 1.62 to 3.6V.
  • ARM Cortex-M3 revision 2.0 running at up to 96MHz
  • Memory protection unit (MPU)
  • Thumb®-2 instruction set
  • Embedded voltage regulator for single supply operation
  • Power-on-reset (POR), brown-out detector (BOD) and watchdog for safe reset
  • 3 to 20MHz Resonator oscillators
  • High precision factory trimmed internal RC oscillator with 4MHz default frequency
  • Slow clock internal RC oscillator as permanent clock for device clock in low power mode
  • One PLL for device clock and one dedicated PLL for USB 2.0 high speed device
  • Sleep, wait and backup modes
  • 1 Serial peripheral interface (SPI)
  • 1 Synchronous serial controller (SSC) (I²S)
  • 1 High speed multimedia card interface (HSMCI) (SDIO/SD/MMC)
  • 3-channel 16-bit Timer/counter (TC) for capture, compare and PWM
  • 4-channel 16-bit PWM (PWMC)
  • 32-bit Real-time timer (RTT) and real-time clock (RTC) with calendar and alarm features
